The purpose of this study is to investigate the effect of number representation activities using computer software on young children's ability in mathematics. The effect of the number representation activities using computer software will be shown differently according to the age. The effect of the number representation activities using computer software will be shown differently according to the genders. The result of this study has shown that it gives a positive influence to the young children's mathematical ability.

This study analyzed students' mathematical noticing in high school sequence classes based on students' two perceptions of sequence. Specifically, mathematical noticing was analyzed in four aspects: center of focus, focusing interaction, task features, and nature of mathematics activities, and the following results were obtained. First of all, the change pattern of central of focus could not be uniquely described by any one component among 'focusing interaction', 'task features', and 'the nature of mathematical activities'. Next, the interactions between the components of mathematical noticing were identified, and the teacher's individual feedback during small group activities influenced the formation of the center of focus. Finally, students showed two different modes of reasoning even within the same classroom, that is, focusing interaction, task features, and nature of mathematics activities that resulted in the same focus. It is hoped that this study will serve as a catalyst for more active research on students' understanding of sequence.

최근 학교 수학교육에서는 창의성 교육을 강조하고 있으며, 창의성을 향상시킬 수 있는 프로그램에 대한 다양한 연구가 진행되고 있다. 이러한 창의성을 향상시키기 위해서는 기계적인 계산에 의해서 한 가지 답을 구하는 학습보다는 탐구하고, 추측하고, 논리적으로 추론하고, 다양한 문제해결 전략을 구사할 수 있는 능력을 키우는 프로그램이 필요하다. 또, 이러한 프로그램이 학생들에게 활동을 통해 다양한 경험을 제공할 수 있다면 더욱 효과적일 것이다. 이 논문에서는 이러한 다양한 창의성 프로그램을 소개하였고, 창의성을 평가하는 방법을 소개하였다.

초등학교에서 7차 교육과정은 2002학년도부터 모든 학년에서 운용이 시작된다. 우리는 새로운 교육과정의 기본 방향을 ‘학습자 중심교육과정’ 이라 하고, 이에 대한 실천방안으로 초등수학교육에서는 ‘활동중심’ 교육과정의 전개를 특징으로 하고 있다. 특히 활동 중심교육에서 가장 중요한 것은 활동의 대상이 되는 교구의 활용이라 할 수 있다. 이러한 교구들 중에서 가장 일반적인 것은 조작교구이므로 이러한 조작교구의 종류와 특징, 성질을 이해하고 활용하는 것은 매우 중요하다. 그러나 실제 학교현장에서는 이러한 자료 활용에 대한 준비와 연구 미흡으로 실천하는데 어려움을 겪고 있는 것이 현실이다. 이에 본 연구에서는 보다 효과적으로 조작교구를 활용 할 수 있는 방안을 제7차 교과서의 내용을 중심으로 탐색하여 구체적인 예를 들어 교수 ${\cdot}$ 학습활동에 도움을 주고자 한다.

In this article we studied the role of spreadsheet in teaching function and modeling activity by some examples and students' activity performed by the six 10th graders. We especially focused the role of spreadsheet in understanding of various kinds of functions and the families of functions, and in the explanation of the given modeling problem situations. The functions of automatic copy, graphic and the cell reference of spreadsheet can be used to make students observe the causes and effects of changes of the various kind of mathematical representations of functions such as algebraic formulas, tables and graphs. Especially those functions give students a chance to identify family of functions by changing the parameters and this may lead them to the discovery of mathematical facts. In modeling activities they play a key role in the stages of the analysis of the model, explanation of the results of model and conjecture of the real world situations. As well as they make students find the rules underlying in the real world by making spreadsheet as simulation environments, which are almost impossible to make in paper and pencil environments, and give them a chance to justify their findings using mathematics.

The purposes of this study were to investigate pre-service mathematics teachers' perceptions of the role of cooperating teachers and teacher interactions during teaching practicum. Thirty-four pre-service mathematics teachers who finished student teaching participated in the study. The researcher collected data from various sources such as a questionnaire, interviews, and written documents. According to the results of the study, more than 50 percent of the participants showed negative responses to all of the questionnaire items on teaching activities or guidance of cooperating teachers. Cooperating teachers mainly played a role in the stage of reflection of student teacher's teaching practice, and they provided specific feedback and guidance of teaching and learning methods and contents. Cooperating teachers played roles as (mathematics) teacher educators, classroom observers, and co-teachers, but their roles as teacher educators or co-teachers should be more stressed for pre-service mathematics teachers' professional development.

From this research, we want to get results that have interested the difference from character of students with the motivation of the learning, confidence and habit through the activity oriented class. When teacher teach students of the learning disability with participant class and activity class, they have encouraged and have positive disposition about mathematics. Therefore teachers should try to give chance doing in mathematics class to students with learning disability.

This study is intended to look into the effects of children's forest math game activities on their understanding of number and space concept. To achieve this, an evaluation was carried out to 20 4-year-old children in each group - experimental group and control group - by an evaluation sheet after forest math game activities during a total of 16 sessions 4 times a week for 4 weeks. The findings are as follows. First, children's forest math game activities had an effect on their understanding of number and space concept. Second, the difference between experimental group and control group showed that the experimental group received higher evaluation in the classifying and order finding items than the control group. It was confirmed that classifying and order finding in the forest math game were factors to help children's mathematical problem-understanding abilities. This implies that their forest math game activities have a positive effect on their mathematical problem-understanding abilities. Consequently, active forest math game activities for children are needed to help them understand the concept of number in the process of classifying task objects and solving tasks in order.
